WANA (Apr 29) – Rafael Grossi, Director General of the International Atomic Energy Agency (IAEA), has alleged that the majority of Iran’s high-purity enriched uranium is likely stored within the Isfahan nuclear complex.

 

In a recent interview, Grossi stated that satellite imagery is being used to assess the aftermath of the June 2025 military strikes by U.S. and Israeli forces against Iranian facilities.

 

The 12-day conflict targeted key sites at Isfahan, Natanz, and Fordow with “bunker-buster” munitions. Although no radiation leaks were reported post-bombing, the material’s status remains unverified.

 

Grossi claims the IAEA believes a significant portion of the stockpile was moved just before the conflict. Reports point to satellite imagery from June 9, 2025, showing a convoy of 18 containers entering a tunnel at the Isfahan Nuclear Technology Center.

 

Grossi noted that while IAEA seals likely remain intact, physical access is currently restricted, making it impossible to rule out the material’s presence. The Agency estimates that of Iran’s 440.9 kg of 60% enriched uranium, roughly 200 kg is located in the Isfahan tunnels.

 

Following the 2025 war, Iran suspended several cooperative measures. Under the “Cairo Agreement,” a new inspection framework, the bombed sites were excluded from regular access. Grossi has repeatedly urged Tehran to reopen these facilities, citing Iran’s obligations under the Non-Proliferation Treaty.

 

To address these concerns, the IAEA chief confirmed that the Agency has held discussions with Russia and other international partners regarding the possibility of transferring Iran’s enriched uranium abroad.

 

Grossi emphasized that it is vital for the material to either be removed from Iran or blended down to a lower purity. While the IAEA participated in nuclear talks in February, recent Oman-mediated diplomacy collapsed after the U.S. resumed military strikes.

 

Iran reportedly seeks the lifting of the U.S. naval blockade and the stabilization of the Strait of Hormuz as prerequisites for deeper nuclear discussions. Grossi noted that while both U.S. President Donald Trump and Iranian leaders express an interest in a deal, they remain at a frustrating impasse over which side must act first.

 

While Grossi warned last year that Iran’s stockpile could theoretically provide enough material for 10 nuclear warheads, Tehran maintains its program is strictly for civilian use. Iranian officials emphasize that nuclear weapons are excluded from their national defense doctrine.

 

Grossi insisted that any lasting political agreement must be centered on comprehensive IAEA inspections and a clear display of political will from all involved parties.
